A new kitten can change every room in a dog's familiar world. The safest welcome begins before the first meeting.The New Kitten in a Dog Home Plan gives families a humane, readiness-gated system for protecting a vulnerable newcomer while teaching the resident dog how to notice, disengage, and share space calmly.Start before pickup day with a complete kitten safe room, a resident-dog history screen, protected escape routes, barrier handoffs, and a first-seventy-two-hours plan. Then progress through scent exchanges, room rotation, closed-door routines, brief visual access, voluntary look-and-return, and carefully controlled shared-space sessions.Thirty reusable missions each include an observable outcome, setup, resident dog-side and kitten-side roles, step-by-step actions, a readiness gate, an easier option, a daily-life transfer, and a clear safety stop. Fifteen print-friendly tools help you record both animals instead of relying on hope or a fixed calendar.You will also find small-home adaptations, multiple-dog protocols, kitten-play planning, troubleshooting for staring, barking, hiding, hissing, and chasing, plus a kitten-growth audit and ninety-day maintenance system.Protect the kitten's choices. Teach the resident dog to disengage. Open only the gate both animals pass.
